SAMUEL L. VALENTINE, 0E BANGOR, MAINE.

IIVI PROVEM ENT IN WATER-WH EELS.

Specication forming part of Letters Patent No. 3,855, dated December 12,1844.

To all whom it may concern:

Be it known that I, SAMUEL L. VALENTINE, of Bangor, in the county ofPenobscot and State of Maine, have invented a new and useful Improvementin Water-Wheels, in the c0n struction of what I denominate a CentrifugalReversing Tater-Wheel g and I do hereby declare that the following is afull, clear,and exact description thereof, reference beinghad to theaccompanying drawings, which form a part of this specicatiomin which-Figure l is a side view, and Fig. 2 a perspective. Y .l

The nature of my invention consists in forming a spiral bucket-wheelWithout any top or bottom, each bucket extending into the shaft andtheir ends supported by rims, as hereinafter described. Thisconstruction permits the Wheel to be run'either as a right or left handwheel by simply reversing it on the shaft without in any Way alteringthe patterns.

The construction is as follows: The hub a can be made either for an ironor wooden shaft and projects sufficiently at each end and beyond theface of the wheel to receive a stout wrought-iron ring. From this hubthe buckets b project outward in a spiral curve to the periphery of thewheel and having their cross-section parallel to the shaft, Theyterminate in a tangent line to the outer circumference of the Wheel, andat this point they are connected with each other by two iat rings c, oneon each side, which extend up the buckets far enough to support them andare scalloped out between the buckets for admitting the water morefreely thereto. Near the outer edge of these rings their faces allroundrun close to the bottom or side plate or table to prevent leaking, Whilethe table supports the whole weight of the water, and thus relieves theWheel from the load that tends to impede its action when used as ahorizontal wheel.

When the wheel is placed vertically, it is put between two cisterns andreceives the water from both sides in equal quantities, which isdischarged at the periphery in either position, vertical or horizontal.VIt can be made to turn in a contrary direction by simply ref versing iton the shaft.

What I claim as my invention, and desire to secure by Letters Patent,is-

The water-wheel constructed as herein described, the buckets of whichare on a line ex-V actly parallel with the shaft in their cross-sectionand extend into the center, with flat rings around their periphery andwithout any shrouding beyond the outer rings toward the center, thewhole being arranged so that the wheel can be made to run either way, inthe manner and for .the purposes herein set forth, combined with theflume on each side there of, as herein specified.
